A prey in front of a predator would be silent in fear. It was common for cowering to happen since everything about the predator was dangerous. The surrounding aura and pressure, and also the minions he had.
But Lucas wasn't just a simple predator. He was rare to consider as he was not just profound in Shadow Art and Mystical Arts, but he was also an Emperor Spirit Realm cultivator. This instance just made the officials silent. They didn't know what to do in front of Lucas, their predator.
Everyone was on the edge of their seats as Lucas stared at Del Dai, curious about how he could remain rational and calm. Lucas just opened a path for the expedition teams to join the people inside the Shadow Prison. And as they joined together, their minds started to question their lives and their purposes.
